Datadog and Splunk are often evaluated together by teams building out their reliability stack. Datadog (cloud-scale monitoring and security platform, founded 2010) is typically a fit for DevOps Teams, SREs, and Platform Engineers, while Splunk (enterprise observability platform for logs, metrics, traces, and security data at scale, founded 2003) leans toward Enterprise SRE, Security Operations, and Platform Engineering. Both cover 13 of the same core capabilities, so the decision usually comes down to where they diverge.
